The Geirangerfjord is one of Norways absolute major tourist destinations, and with no less than 3 large cruise ships anchored at the end of the fjord, you’ll get a very good perspective on dimensions of the surrounding nature. Please observe the ships funnels closely?
See the smoke pouring out just about continuesly? That’s poisenous carbon oxides, and its heavier than normal air. With the tall mountains all around, it has nowhere to go!
